VerizonWe've already heard from Verizon's CEO Lowell McAdam that the carrier was planning to offer shared data plans. And leaks have indicated that the carrier is already prepping its backend system for the change. Now CFO Fran Shammo has narrowed down the time frame a bit for us, telling a group of investors that family data plans should debut towards the middle of the year. But, he was quick to clarify this isn't as simple as setting a launch date. The shift to the new billing system will take time and not everyone will be migrated on day one. Still, Shammo indicated it will be an important part of the ongoing transition to 4G and its future plans for mobile dominance.

Update: We mistakenly identified Fran Shammo as the CTO when, in fact, he is the CFO.
